I just finished applying the hotifx 4 for my 9.01 coldfusion 32bit server on a Unbuntu box and after restarting CF and Apache I noticed the Admin page comes up blank, otherwise CF is working perfectly.

Error [jrpp-2] - Element ESAPIUTILS is undefined in a Java object of type class [Ljava.lang.String;. The specific sequence of files included or processed is: /var/www/CFIDE/administrator/index.cfm, line: 55
Any idea how to overcome this and bring back the admin page?

I did notice the blank admin page if you view the source you can see code so its there its just not rendering for some reason.
